Tucson to Phoenix by Train?

From here to there, faster: High-speed rail needed for speedier future along the Tucson-Phoenix commute

The author suggests subsidizing the line, which would whisk passengers between the two cities in 45 minutes, with a toll on the I-10.

This coupled with some real Smart Growth

A successful rail system isn't going to magically pay for itself. I'd think the prospect of unbridled growth in Arizona would make the idea of spending a few $$$ on a rail system more attractive. A feasible rail system isn't going to hapen without both vision and commitment- and money, of courss. Isn't a rail link between Tucson and Phoenix something which would work? I'll readily agree that a Tucson-Los Angeles train might not be the best idea in the world, but if states were to develop their own high-speed rail lines, they might eventually connect in some cases. I'd just like to see something done in Arizona before the sprawl gets any worse.
